FRED WILLIS HILL, OF LYNIDONVILLE, NEW YORK.

BED-SPRING.

Application filed June 9, 1915.

To all whom it may concern:

Be it known that I, FRED WV. HILL, a citizen of the United States, and a resident of Lyndonville, in the county of Qrleans and State of N w York, have invented a new and Improved Bed-Spring, of which the following is a full, clear, and exact descrip tion.

This invention relates to furniture and has particular reference to spring cushions such as are used for bed mattresses, upholstered chairs or couches, and the like.

Among the objects of the invention is to provide a'spring mattress frame having a joint so that one part may be positioned at an angle to another part and so supported in position as to provide a head rest in the case of a bed mattress or couch, or a back rest in the case of a chair or the like, but having facilities whereby the movable section may be restoredto normal position in the same plane as the relatively fixed part, by simply pulling upon a cord or cords at one end of the structure.

The foregoing and other objects of the invention will hereinafter be more fully described and claimed and illustrated in the drawings forming a part of this specification in which like characters of reference indicate corresponding parts in all the views, and in which Figure 1 is a plan view of suflicient of a bed spring to show the characteristic features thereof. Fig. 2 is a vertical longitudinal section on the line 22 of Fig. 1; and Fig. 3 is a view similar to Fig. 2, but indicating one section mzoved relatively to the main portion of the device.

The several parts of this device may be made of any suitable materials, and the rela tive sizes and proportions, as well as the general design of the mechanism, may be varied to a considerable extent without departing from the spirit of the invention hereinafter more fully described and claimed.

Referring more particularly to the drawings, I show at A and B relatively fixed and movable frame sections adapted to lie in substantially the same plane in normal position as shown in Figs. 1 and 2, but with the provision that the section B may be set and temporarily locked at any desired angle with relation to the frame A.

The frame A comprises longitudinal rails 10 and transverse bars or slats 11' rigidly Specification of Letters Patent.

connected in any suitable manner. The rails 10 may also be connected at their ends by a beam 12. As shown in the drawings, 1 provide at least four of the longitudinal rails l0 arranged in pairs at the opposite longitudinal sides of the frame, and the rails of each pair have slots 13 formed therein in the same plane and extending longitudinally of the frame.

The movable member B comprises longitudinal rails 14 preferably of the same num.

as a plurality of coil springs 16 connected to one another by lighter springs 17 The longitudinal rails let of the movable section may be regarded as arranged in pairs corresponding to the aforesaid pairs of rails 10 at the sides of the frame. Each pair of rails ll is fitted at its inner end with a pivot rod 18 whose ends extend laterally through the slots 13 of the pair of rails 10 between which the pair of rails 14 is disposed. The rod 18, therefore, constitutes a pivot around which the member B is adapted to swing through a limited angle, but the slots 13 provide for a certain movement of the rod 18 longitudinally of the bars or rails 10.

Bracing links 19 are pivoted at 20 to the outside rails 10 of the frame A-and at their inner ends at 21 to the intermediate portions of the outermost rails 14. The points 20 constitute fixed pivot points for the links 19 and movable section B, and together with the pivot rods 18 insure permanent connection between the two main sections A and B. When the outer end of the movable section B is lifted, throwingthe section at an angle to the main section A, the pivot points 21 are correspondingly elevated, the section B turning around the rods 18 as fulcrums, and such movement causes the pivot rods'18 to approach the pivot points 20, the rods 18 sliding along the slots 13 as shown in Fig. 3. If desired, however, a single pivot rod 18 may extend across to accommodate both pairs of rails 14. p I

As a convenient and reliable means to control the position of the rods 18 and thereby lock the movable section B in any position to which it may be elevated at an angle to the main section A, I employ a pair of toothed bars or racks 22 pivoted permanently at 23 to certain of the rails 10. The teeth 24 of the racks 22 project downwardly and ride or snap over the rods 18 While the latter are being moved outwardly thereunder. The front or inner ends 25 of the racks 22 cooperate with levers 26, formed preferably of spring metal, such as is employed in the springs 16, one end 27 of each of the levers being free. The intermediate portion of each lever is guided in a keeper 28 while the opposite end is passed laterally through the end 25 of he adjacent rack forming a sort of crank at 30 and is connected at its extreme end to a trip bar 29 extending practically all the way across the entire frame and having corresponding connection to the opposite rack and lever 26.

One or more cords or other flexible connections 31 extend beneath the trip bar 29 and outwardly to the points 32 where they are connected to the outer end of the auxiliary frame B for convenience. The inner or opposite ends of the connections 31 are looped over several of the springs 16 as shown at 33 as an anchor. When the sec- .tion B is elevated, and it is desired that it be lowered, the operator has access at the upper end of such section to the connections 31, and a pull upon the same will lift up upon the bar 29 as shown in dotted lines in Fig. 3, releasing the rack from the rods 18 and hence allowing the frame B to be dropped into normal position as shown in Fig. 2. The levers 26 swing around the keepers 28 as fulcrums, and hence such levers act as levers of the second. class, lifting upon the ends 25 of the racks.

The device is simple of construction and easy of operation, and the improvement may be provided at a reasonable cost.

I claim:

In a bed spring, the combination of stationary frame members, a movable frame member comprising longitudinal rails connected to the stationary frame, said stationary frame including longitudinal parallel rails having slots formed transversely therein in the same plane, a pivot rod carried by the movable frame rails and movable along said slots, a pair of links connecting the movable frame to the stationary frame, a pair of racks pivoted to the stationary frame and movable in vertical planes into and out of engagement with the transverse rod, and means operable from the end of the bed spring to release the racks to permit the adjustment of the movable frame, said last mentioned means including a pair of levers of the second class fulcrumed in and slidable along keepers secured to the longitudinal rails of the mainframe, a transverse bar connected to the free ends of the levers, the middle portions of the levers being bent laterally into cranks connected to the free ends of the racks, and a flexible member extending from the end of the bed spring beneath the transverse bar, substantially as shown and described.
